-( 64 )- 



following description is made from the Saghalien specimens. 



Teleutosori are eveoly scattered or gregarious on the under-surface of the leaf, 

 roundish or ellipsoidal in shape, naked, powdery and blackish brown in colour. 

 Teleutospores are deeply constricted at the septum. The upper cells are globose or 

 ellipsoidal, while the lower ones are globose or ovoidal, rounded at both ends, and 

 not thickened at the apex, 30 45x17 27/4. Epispore is covered with pointed 

 warts, dark brown in colour. Pedicels are hyaline, deciduous and short, sometimes 

 25 ft in length.

REMARKS. The present species was first found on Thalictrum alpinum L. in 

 Scandinavia. It is of special interest to know that the same fungus is found in our 

 alpine regions on Thalictrum alpinum var. stipitaium and T. tuberiferum. The 

 teleutosori on the former species are scattered on the under surface of the leaf 

 and on the petiole. They appear as compact and blackish spots as in Rhytisma, as 

 JOHANSON (6) has already stated in his remarks on this species. The sori are 

 covered by epidermis and divided into many small compartments by a thick bed 

 ot brown paraphyses. Teleutospores are liuear-clavate, fusiform or linear in shape, 

 rouud.nl or apiculate and thickened (49 /it) at the apex, attenuated at the base, 

 not or slightly constricted at the septum, and smooth. The typical ones measure 

 o5 64x7 14 p. Pedicels are light brownish in colour, short and subdeciduous. 



While the telentosori of the fungus on Thalictrum tuleriferum are not only
